In Top-down sites, there are many open sections around the tower crane installed on the steel frame. The open section near the tower crane may cause slab cracks and deformation of the steel frame members installed in the open section due to earth pressure. Therefore, in the field, additional consideration during construction of the open section near the tower crane should be considered.
